MUFE HD Foundation and white cast in flash photography

I was just curious about white casts we may get in flash photography due to SPF in our foundation. From what I've read, titanium dioxide is the ingredient that cause a white cast in these flash photos. However, MUFE HD and Mat Velvet+ say there is no SPF; but titanium dioxide is included in these foundations. I was wondering if anyone has had experiences with a white cast using these two MUFE foundations in flash photography. I know the HD foundation is made to be under the pressure of photo lighting; so I just wanted to see if anyone else can help me wrap my head around this.
